Is this a sign of jealousy?

The guys involved I have given fake names.

I am very close to a guy friend called, Connor, however we had an argument and we did not speak for 2 weeks until today, when he was speaking to the girls I work with during class.

During this class, me and Connor normally work together, however, we got seperated onto different jobs. I was working on my own until the girls offered to help. Andy and Tom who I get on well with, decided to join us.

I was telling Andy and Tom what to do, as Connor was watching, he then came over and said "looks like a lot of fun is going on over here" I snatched the brush from Andy and said, "yes there is". Connor helped me abit, tried to distract me but I went back to Andy and Tom - Connor then went off, I found him working with other people and he seemed very annoyed.

I asked him what was wrong and he said, nothing i am always like this. When it was just him and me, he then starts to make comments on another girls body..

He spoke to everyone fine in my group other than me after he saw me laughing with Andy.

I kept asking him what was wrong and how I noticed he was fine with everyone, but me. He said, How do you know that I am fine with them? I said, well you are laughing and joking with them two but annoyed with me, then he told me too just leave it.

Does this seem like jealousy? Apologies for this being long, just wanted people to have the full story. Thank you.
